Supercurrents and Brane Currents in Diverse Dimensions

Understand

We systematically analyze all possible supersymmetry multiplets that include the supersymmetry current and the energy-momentum tensor in various dimensions, focusing on N=1 in four dimensions.

• The most general such multiplet is the S-multiplet, which includes 16 bosonic and 16 fermionic operators.
• In special situations it can be decomposed, leading to smaller multiplets with 12+12 or even 8+8 operators.
• Physically, these multiplets give rise to different brane charges in the supersymmetry algebra.
